Spraying device

摘要

A rotary spray device includes a seat body having an entrance and a spray head body in which a fluid passage is provided. The rotary spray device further includes at least one impeller. The entrance communicates with the fluid passage by a fluid chamber. The impeller is located within the fluid chamber and is rotated with the spray head body. The spray head body is rotatably connected with the seat body. Preferably, the spray head body has eccentric spray nozzles, and the minimal distance is not zero between the center lines of the eccentric spray nozzles and the rotation center line of the spray head body, and the center lines do not parallel the rotation center line. The rotation center line of spray head body is an axis about which the spray head body rotates relative to the seat body. The spray device according to the present invention rotates the spray head body by the drive of the fluid energy, to perform a pressure pray, and may also spray leak liquid through the rotation clearance. It has a simple, compact structure, and may achieve a good effect.

主权项

1. A rotary spray device comprising a seat body, a spray head body and an impeller, wherein said spray head body is rotatably connected with said seat body, wherein said seat body has an inner hole, an entrance communicating with an external pressurized flow source, a fluid passage, and a plurality of spray openings, and a plurality of atomizing cores provided on said spray head body, wherein said spray openings are arranged to communicate with said fluid passage, wherein at least two of said spray openings are eccentric spray openings to define an eccentric distance between a projection of a centerline of said eccentric spray openings on a plane perpendicular to an axis of said spray head body, said spray device further comprises an impeller rotating together with said spray head body, in which a rotational direction of said impeller is identical to a tightening direction of a connection thread on said spray head body of said spray device, wherein said impeller is located between said inner hole of said seat body and said fluid passage, wherein an open direction of said eccentric spray openings is opposite to a rotation direction of said spray head body pushed by said impeller.
